From: Tvrtko Ursulin Date: Thu, 1 Dec 2016 14:16:40 +0000 (+0000) Subject: drm/i915: dev_priv cleanup in bridge/bar/mmio init code X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=da5f53bf3c3ad5ffcb88b2892a9c02ece2ad140f;p=linux-beck.git drm/i915: dev_priv cleanup in bridge/bar/mmio init code dev_priv is more appropriate for these so converting saves some lines of source. v2: Commit message and keep the pdev local variable.
